(a) Draw an activation energy diagram for this reaction under catalyzed and uncatalyzed conditions and explain what it means for the activation energy to be lowered from 18 to 13 kcal/mol by ferric ions but from 18 to 7 kcal/mol by catalase. Please draw in the space provided below. (b) Suggest two properties of catalase that make it a more suitable intracellular catalyst than ferric ions.

Q5) H2O2, decomposes to H2O and O2. 2H,O2→ 2H20 + O2 The activation energy, EA, for the uncatalyzed reaction at 20°C is 18 kcal/mol. The reaction can be catalyzed either by ferric ions (EA 13 kcal/mol) or by the enzyme catalase (EA 7 kcal/mol). (a) Draw an activation energy diagram for this reaction under catalyzed and uncatalyzed conditions and explain what it means for the activation energy to be lowered from 18 to 13 kcal/mol by ferric ions but from 18 to 7 kcal/mol by catalase. Please draw in the space provided below. (b) Suggest two properties of catalase that make it a more suitable intracellular catalyst than ferric ions. (c) Suggest yet another way that the rate of hydrogen peroxide decomposition can be accelerated. Is this a suitable means of increasing reaction rates within cells? Why or why not?
